Of course he plans out what he is going to do in the end zone after scoring a touchdown, because, Odell Beckham Jr. said, “You never want to look bad on TV.’’

There is not really any fear Beckham looking bad anywhere, anytime. The rookie receiver is topping himself week after week and, finally, he is bringing the Giants along for the ride.

“Nothing this guy does amazes me at this point,’’ Antrel Rolle said.

Eli Manning and the Giants put up three touchdowns Sunday against the Redskins and Beckham hauled in every one. He gave his team the lead in the first quarter. He put the Giants ahead for good in the third quarter. He sealed the deal in the fourth quarter. It is not known if he helped clean up MetLife Stadium after the Giants finished off a 24-13 victory, but his fingerprints were on just about everything.

“Well, I’m cheering for him every time he gets the ball,’’ coach Tom Coughlin said. “He does the best he can and can excite everybody in the building.’’

It was tough to inject much excitement into this matchup featuring teams that came in with a combined seven victories, especially in a yawner of a first half that ended with a bang — a Redskins touchdown was taken off the board, prompting an angry scene on the field — and triggered a second-half resurgence as the Giants (5-9) put together back-to-back wins, sacking Robert Griffin III five times after halftime and seven times altogether.

Certainly Coughlin wants to return for a 12th year as Giants head coach and continue to work with Beckham, who was unstoppable with 12 receptions for 143 yards and scoring catches of 10, 35 and 6 yards. He has 23 receptions for 273 yards in his last two games and, despite missing the first four games, is forging his way to the NFL’s Rookie of the Year award. He set a franchise rookie record with 972 receiving yards.

“That is great,’’ Beckham said. “That is something that is always in the back of your mind. It is an honor.’’

Beckham is about the only thing the Giants had going for them offensively in the first half, as they trailed 10-7. They caught a huge break, as it sure looked as if they went down 17-7 after RG III — subbing for injured Colt McCoy (neck) — scrambled and leaped to the right pylon, just eluding a pursuing Jason Pierre-Paul for what was ruled a 7-yard touchdown as time expired in the second quarter.

The replay review seemed like a mere formality, but referee Jeff Triplette returned to the field with a shocker: Griffin had lost possession of the ball, regained possession but did not have full possession as he inched into the end zone. Thus, the touchdown was wiped out and instead became a touchback because Griffin was ruled to have fumbled the ball out of the end zone.

“It was a touchdown … that’s how we all felt,’’ Griffin said. “If the ball passes the plane and you have control of the ball, it’s a touchdown in every game that I’ve ever seen, but they decided it wasn’t today.’’

Dominique Rodgers-Cromartie admitted: “I thought it was good, to be honest.’’

Rolle said he got a good look at the end of the play and, “I saw the ball come loose, without a doubt. I wasn’t confident it would be over turned but I did see the ball come loose.’’

The Redskins did not concur. They went ballistic, lingering on the field to encircle and berate Triplette and then field judge Alex Kemp as the Giants gleefully ran off. In the scrum, veteran receiver Santana Moss went so hard at the officials that he was hit with two penalties and ejected, according to Triplette, for “very, very inappropriate language that was derogatory towards the official.’’

The 30 yards in penalties put the Giants on the Washington 35 for the second-half kickoff — prime onside kick territory. Josh Brown executed it to perfection and Chandler Fenner recovered the bouncing ball on the Redskins 17-yard line. The Giants could only marginally cash in, though, as they settled for a Josh Brown field goal to make it 10-10.

The Redskins (3-11) went ahead 13-10 late in the third quarter before the Giants finally awakened and dominated. Rookie cornerback Bashaud Breeland, abused all day, was hit with a 26-yard pass interference penalty trying to hang with Beckham and moments later Beckham split the defense and Manning hit him in stride for a 35-yard catch-and-run scoring play to put the Giants ahead 17-13.

After two more three-and-outs by the enlivened Giants’ defense, Manning completed a 76-yard drive by hitting Beckham with a 6-yard slant, with cornerback David Amerson no match for Beckham in the end zone.

Cue the gushing about Beckham, although Manning tried to be restrained.

“You don’t want to get his head too big too early right now,’’ Manning said, “but he’s got a lot of skills.’’
